Growth and Innovation Policy in a Small, Open Economy: Should You Stimulate Domestic R&D or Exports?

In small and open economies, absorption of foreign knowledge through international trade often plays a more important role for domestic innovation and growth than investment in domestic R&D. This suggests that trade policies can increase knowledge spillovers from abroad. Public support to R&D can be motivated both by positive internal knowledge externalities and by its ability to expand absorptive capacity. This dynamic, empirical, general equilibrium analysis models these interplays between R&D, trade and productivity. It compares public R&D support and export promotion of R&D based products with respect to long term growth and welfare impacts. We find that export promotion is inferior to R&D support in spurring R&D. However, it is not outperformed in terms of welfare generation. The reason is that existing and politically persistent policy interventions create inefficiencies that can be counteracted by R&D-based export promotion as a second-best policy.

Can a Carbon Permit System Reduce Spanish Unemployment?

Abstract: This paper addresses the frequently articulated worry for the unemployment impacts of abating CO2 emissions. The Spanish economy is ridden by unemployment rates well above the EU average. At the same time the deviation from EU's intermediate emission goals is more serious than for most other EU countries. We use a CGE model that includes a matching model with two types of labour, and which allows for different pricing rules and returns-to-scale assumptions. Our findings are optimistic. Due to low labour intensity in most of the dirty, Spanish industries, the unemployment rate is hardly affected by introducing an emission permit system. Further, by recycling the sales revenue into reduced labour taxes, unemployment rates fall. Contrary to other studies of Europe, we find that reducing payroll taxes on skilled labour is the most successful in reducing unemployment rates, both through increasing demand and through dampening the supply response to rising wages. All the recycling schemes also generate dividends in terms of welfare, but none offset the abatement costs entirely.
